Description

Pulling aid and server bracket with same Technical Field The application relates to a pull-out aid, in particular to a damping type pull-out aid. The application also relates to a server bracket comprising the pull-out aid. Background A pull aid (also referred to as a boost/pull aid) is a device that assists a user in inserting or extracting a first object into or from a second object. One common application scenario of the unplugging assisting device is a server, and is mainly used for improving the plugging convenience of a server module. However, during the process of pulling the server module out of the server rack, the server module may be suddenly released or quickly ejected due to the quick trip, which may cause damage to the server module or injury to an operator, as well as damage to other modules inside the server. Thus, the extractor aid is not only needed to assist in extracting the server module, but also to provide appropriate braking to ensure that the server is not damaged during extraction, or to disrupt the stability of the overall system, or to injure the operator. However, conventional extractors (e.g., of a double pivot design) have difficulty achieving all of the requirements. Disclosure of utility model According to an aspect of the application, there is provided a pull-out aid comprising a base plate, a handle pivotably connected to the base plate, and a jaw pivotably connected to the base plate, and a surface of the jaw facing the handle being provided with a clamping post, wherein the clamping post is configured to be able to cooperate with the handle such that the jaw and the handle pivot in the same direction. In one embodiment, the extractor further includes a trigger member pivotally connected to the base plate, and an elastic member mounted to the trigger member and configured to urge the trigger member against the handle. In one embodiment, the trigger includes a receiving recess in which the post is capable of fitting. In one embodiment, the extractor further comprises a fastening assembly configured for locking the handle to a first object, wherein the fastening assembly comprises a fastener comprising a head and a stem mounted on the handle and a locking ratchet mounted on the first object, the fastening assembly having a locked state in which the stem is inserted in the locking ratchet and an unlocked state in which the stem is separated from the locking ratchet. In one embodiment, the extractor further comprises a washer disposed on a side of the jaws facing away from the post, wherein the washer is configured to create sliding friction for pivoting of the jaws. In one embodiment, the extractor further comprises a washer disposed on a side of the handle facing away from the jaws, wherein the washer is configured to create sliding friction for pivoting of the handle. In one embodiment, the extractor further includes a cover fixedly connected to and spaced apart from the base plate to define a receiving cavity therebetween, the handle, the pawl, and the trigger being at least partially located in the receiving cavity. In one embodiment, the handle has a pushing end located outside the accommodating cavity, the claw has a limiting end, the touch piece has a touch end, the limiting end and the touch end can extend out of the accommodating cavity in the pivoting process, and the pushing end, the limiting end and the touch end can be matched with a second object in the pulling or pushing process. In one embodiment, the second object comprises a limit groove, the handle is provided with a folding position and an operation position, wherein when the handle is in the folding position, the limit end is abutted with one end of the limit groove, and the pushing end pushes the second object in the process of pivoting the handle from the folding position to the operation position, and the second object causes the clamping jaw to pivot through the cooperation of the limit groove and the limit end. In one embodiment, the handle further has a fixed position, wherein the limit end is separated from the limit groove when the handle is in the fixed position, and the second object pushes the trigger end to pivot the trigger against the elastic force of the elastic element during the process of returning the handle from the fixed position to the operation position, so that the handle is allowed to pivot towards the operation position, and the handle is pivoted towards the operation position to drive the claw to pivot through the clamping column. In one embodiment, the handle includes a grip, and a link pivotably connected to the base plate, wherein an end of the link connected to the base plate is formed in a cam shape, and the link includes a contact portion, a boss portion, and a stopper portion at the cam-shaped end, and wherein the claw can push the contact portion through the clamping post to pivot the handle during pivoting.
