  8. 8. The glue extrusion tool of claim 7, wherein the driving member is sleeved outside the ram and is movable axially along the ram to drive the fixing member to expand and contract outwardly and inwardly, and/or wherein the driving member comprises a barrel and first and second arms projecting radially from the barrel, the fixing member and the first and second arms being cooperatively connected to the shaft by two sets of grooves.
  9. 9. A glue extrusion tool according to claim 3, wherein the handle is foldably provided to the body and/or the rocker arm is foldably provided to the body.
  10. 10. The glue extrusion tool of claim 9, wherein the handle and the body are provided with a rotational limit mechanism, the handle is provided with a drive portion that disengages the rotational limit mechanism from limit, and the drive portion is disposed at a first end of the handle that is connected to the body.

Description

Glue extrusion tool Technical Field The disclosure belongs to the technical field of hardware tools, and particularly relates to a glue extrusion tool. Background The caulking gun (glue gun) is a common tool for house decoration and repair, and the glue used with the caulking gun is sealed in a rubber tube (tubular shell). One end of the rubber tube is a rubber outlet tip, the other end of the rubber tube is a piston bottom, and the piston bottom is axially extruded towards one end of the rubber outlet tip, so that the glue can be extruded from the rubber outlet tip. When the glue pipe is used, the glue pipe is fixed on the caulking gun, a user can pull the rocker arm of the caulking gun to drive the ejector rod to push the piston bottom of the glue pipe, and the piston bottom moves axially to extrude glue. The rubber tube length and the quality are great, need fix on the caulking gun through longer constraint structure, consequently lead to the length of caulking gun itself great, this will lead to the space that the caulking gun occupy great, is unfavorable for storage and transportation. Disclosure of utility model The present disclosure is directed to a smaller length glue extrusion tool. In a first aspect, a glue extrusion tool is provided for receiving a hose and pushing a bottom end of the hose, the bottom end having a recess, comprising a main body, an extrusion mechanism, a backstop mechanism, and a hose securing mechanism. The main body is provided with a receiving end for engaging the bottom end of the rubber tube, the extruding mechanism comprises a push rod and a rocker arm, the push rod movably penetrates through the main body, the first end of the push rod is used for pushing the end face of the bottom end of the rubber tube, the rocker arm is hinged with the main body and is configured to swing within a preset range, the rocker arm is associated with the push rod to be capable of intermittently driving the push rod to move towards the receiving end of the main body during swinging, the retaining mechanism is associated with the push rod to prevent the push rod from moving reversely along the direction of the receiving end of the main body, the rubber tube fixing mechanism is arranged at the receiving end and comprises a fixing piece movably arranged at the receiving end, the fixing piece can move from a release position to an open position, the outer contour diameter of the fixing piece in the open position is larger than the outer contour diameter of the fixing piece in the open position, and the fixing piece forms limit on the side wall of a concave part of the bottom end of the rubber tube in the open position. In one possible implementation, the securing member has an axial stop feature configured to axially stop the bead of the hose when the securing member is in the open position.

In combination with the above possible implementation manner, in another possible implementation manner, the retaining mechanism and the fixing mechanism share a release lever, and the release lever acts on the ejector rod in the first position to limit the reverse movement of the ejector rod along the direction of the receiving end of the main body, and releases the limit of the ejector rod in the second position. In combination with the above possible implementation, in another possible implementation, the release lever acts on the securing member in the first position to hold it in the open position. In combination with the possible implementation described above, in another possible implementation, the fixing element is hinged to the body, having a free end for acting with the hose and a connection portion for receiving the action of the release lever, or comprises a central portion and a resilient portion extending radially from the central portion, the resilient portion having a free end for acting with the hose and a middle portion for receiving the action of the release lever. In combination with the above possible implementation manner, in another possible implementation manner, the device further includes a transmission member, wherein the transmission member is associated with the fixing member, and the release lever is obliquely abutted against the transmission member, and the release lever enables the transmission member to drive the fixing member. In combination with the above possible implementation manner, in another possible implementation manner, the transmission member is sleeved outside the ejector rod and can move along the axial direction of the ejector rod to drive the fixing member to expand
