[0006] Furthermore, the projection of the lubrication safety fitting groove in the up-down direction is located within the region of the projection of the sliding adjustment fitting groove in the up-down direction.

[0007] Furthermore, a lubrication transition safety groove is provided at the central axis position of the main body mounting fitting seat to connect two adjacent sliding adjustment fitting grooves.

[0008] Beneficial effects of the utility model:

[0009] The utility model provides a lubrication groove at the adjustment fitting position, and forms a conical lubrication fitting space between the lubrication position and the adjustment structure, which can provide a precise and safe setting space for the lubricating liquid during use. The lubricating liquid is more evenly matched during use, and it is not easy for the lubricating liquid to flow to the external position, which reduces unnecessary cleaning. The fitting end face position of the adjustment position is provided with a cylindrical fitting structure, which can achieve fitting contact between the cylindrical surface and the plane during adjustment, effectively reducing wear during the adjustment process, making the fitting smoothness during adjustment better, and more convenient during use.

[0018] like Figures 1 to 7As shown, a wear-resistant mating component for a hand tool includes a cylindrical main body mounting mating seat 1 with a central axis in the left-right direction, the upper end of the main body mounting mating seat 1 is a clamping mating support plate 2, and the front of the main body mounting mating seat 1 is provided with sliding adjustment mating grooves 3 that are evenly distributed on the left and right and penetrate the entire front-to-back direction. When in use, they are mated with the adjustment studs of the wrench to adjust the position during use. A cylindrical lubrication safety mating groove 4 that completely penetrates the entire front-to-back direction is provided at the upper right end of the sliding adjustment mating groove 3, which can provide a setting space for lubricating liquid during use. The central axis of the lubrication safety mating groove 4 is perpendicular to the central axis of the main body mounting mating seat 1, which is more convenient during production and processing, and has less impact on the strength of the main body mating position. The intersection of the lubrication safety mating groove 4 and the sliding adjustment mating groove 3 forms a conical lubrication mating transition groove, which can provide uniform lubrication delivery for adjusting the movable mating position during use. The left and right end surfaces of the sliding adjustment fitting groove 3 are inclined bevel structures. The left and right end surfaces of the sliding adjustment fitting groove 3 are provided with integrally formed cylindrical adjustment safety support fitting columns, which can replace the contact fit between planes during adjustment. The fit between the cylindrical surface and the plane ensures smooth fit during adjustment, and improves the wear resistance of the fitting position during use. The central axis of the adjustment safety support fitting columns is located on the end surfaces at the corresponding positions on the left and right sides of the sliding adjustment fitting groove 3, which makes the fitting position more load-bearing and more reliable. By providing a lubrication groove at the adjustment fitting position, a conical lubrication fitting space is formed between the lubrication position and the adjustment structure, which can provide a precise and safe space for lubricating liquid during use. During use, the lubricating liquid is more evenly matched, and it is difficult for the lubricating liquid to flow to external locations, reducing unnecessary cleaning. The cylindrical fitting structure is provided at the fitting end surface of the adjustment position, which can achieve cylindrical and flat contact during adjustment, effectively reducing wear during adjustment, improving the fit smoothness during adjustment, and increasing convenience during use.

[0019] Preferably, the projection of the lubricating safety fitting groove 4 in the vertical direction is located within the area of ​​the projection of the sliding adjustment fitting groove 3 in the vertical direction, so that the lubricating safety fitting groove 4 has less impact on the strength of the main structure and the fitting bearing capacity during use is more reliable.

[0020] Preferably, a lubrication transition safety groove is provided at the central axis position of the main body mounting fitting seat 1, which connects the two adjacent sliding adjustment fitting grooves 3, so that lubrication transition can be performed between adjacent positions, the overall fitting smoothness during use is better, the lubrication is more comprehensive during use, and the smoothness during adjustment can be further improved.

[0021] The above is a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements or substitutions can be made without departing from the principles described in the present invention. These improvements or substitutions should also be regarded as the scope of protection of the present invention.
