Description

Grass trimmer solenoid Technical Field The application relates to the field of garden tools, in particular to a grass mowing machine coil. Background In the field of modern gardening, grass cutters have become an important tool for maintaining lawns. The grass trimmer coil is particularly important as a cutting device of the grass trimmer, and the structure of the grass trimmer coil directly influences the labor intensity and the working quality of operators. The existing wire-knocking paying-off type grass mower coil comprises a coil base, a winding wheel arranged in a coil housing body, a knocking head arranged on the winding wheel, a spring arranged in the winding wheel and a coil cover clamped and fixed with the coil base. When paying off, the knocking head knocks on the ground, so that the reel and the wire shell are separated from each other to generate relative rotation, and paying off is realized. So that a certain gap exists between the solenoid cover and the knocking head. In view of the above-mentioned related art, the inventors consider that when a striking pay-off type grass trimmer is used for trimming grass, weeds enter the grass trimmer coil through a gap between the striking head and the coil cover, and when excessive weed backlog occurs in the grass trimmer coil, the pay-off is easily affected. Disclosure of utility model In order to reduce weeds entering the grass trimmer coil through a gap between the knocking head and the coil cover, the application provides the grass trimmer coil. The application provides a grass trimmer coil, which adopts the following technical scheme: A grass mowing machine coil comprises a coil shell and a reel rotatably mounted in the coil shell, wherein the coil shell comprises a coil base and a coil cover mounted on the coil base, the coil cover is provided with a knocking through hole, the reel is provided with a knocking head arranged in the knocking through hole, an elastic piece is further arranged in the coil shell and drives the reel to always have a trend of moving towards the direction of the coil cover, and a sealing gasket for abutting against the top wall of the inner side of the coil cover is further sleeved at the knocking head. Through adopting above-mentioned technical scheme, through setting up the structure of elastic component and sealing washer for the grass trimmer is in the course of the work, sealing washer butt is on the inboard roof of online covering under the effect of elastic component, thereby realizes the sealed to striking the through-hole, has reduced the weeds along striking the head and strike the internal probability of clearance entering line cladding between the through-hole inner wall, thereby has reduced the grass trimmer and has invaded the grass trimmer solenoid at the operation in-process and lead to the unsmooth probability of the rope of being qualified for the next round of competitions of the grass of grass trimmer solenoid. Optionally, the sealing washer is provided with a plurality of radial arrangement in inner wall circumference and extrudes the anti-skidding dogtooth of butt in the head outer wall. Through adopting above-mentioned technical scheme, the protection dogtooth that sets up on sealing washer's the inner wall helps installing sealing washer at the outer wall of beating the head to help promoting sealing washer at beating the axial positioning of head department. Optionally, the anti-slip convex teeth are provided with anti-slip cambered surfaces matched with the outer wall of the knocking head. By adopting the technical scheme, the anti-skid convex teeth with the anti-skid cambered surfaces are arranged, so that the anti-skid convex teeth are clung to the outer wall of the knocking head, and the axial float of the sealing gasket at the knocking head is further reduced. Optionally, a central convex part is arranged at the center of the reel, a plurality of supporting ribs are arranged at the circumference of the central convex part, and the sealing gasket is provided with an arrangement groove for arranging the supporting ribs. By adopting the technical scheme, the sealing gasket is provided with the arrangement groove for arranging the supporting rib plates, so that the supporting rib plates can be arranged in the arrangement groove of the sealing gasket, and the probability of circumferential rotation of the sealing gasket is reduced. Optionally, a rotating column is arranged at the bottom of the coil base, a rotating hole for arranging the rotating column is formed in the bottom of the coil, a spring hole for arranging the elastic element is coaxially formed in the top end of the rotating column, one end of the elastic element is abutted to the top of the rotating hole, and the other end of the elastic element is abutted to the bottom surface of the spring hole. Through adopting above-mentioned technical scheme, disclose the mounting structure of coil base and coil cover department elastic component,
