[0002] The shovel teeth installed on the excavator are consumable parts, which need to be replaced in time according to the wear and tear. The shovel teeth are usually cast, and there will be a large number of holes and burrs on the outer wall after casting. The existence of these will affect the quality of the shovel teeth. At present, the shovel teeth are often processed by shot peening. Since there is a slot at the root of the shovel teeth, it is inconvenient to position the shovel teeth during surface treatment, which increases the difficulty of slot processing. In addition, when performing shot peening, a rod is often inserted into the installation hole of the shovel teeth, and then locked by a nut. However, this existing method is cumbersome to operate during fixing, thereby reducing the efficiency of shot peening. Utility Model Content

A plurality of concave plates 2 are installed on the outer periphery of the middle plate 1, and a mounting block 29 is installed on the other end of the concave plate 2, and an outer plate 30 is installed on the other end of the mounting block 29, and a positioning block 31 is provided on the outer plate 30, and a clamping block 33 is provided at the end of the positioning block 31, and a positioning end block 32 is provided on the upper wall of the clamping block 33, and a clamping groove 34 is provided on the clamping block 33, and the clamping groove 34 is in a V-shaped structure. The outer end of the clamping groove 34 is open, and a screw rod 23 is rotatably arranged on the other end of the concave plate 2, and the threads at the two ends of the screw rod 23 are rotated in opposite directions, and L-shaped seats 22 are provided at the two ends of the screw rod 23, and a pair of guide rods 21 are provided on the L-shaped seat 22, and the guide rods 21 pass through the concave plate 2, and guide sleeves 20 are provided on both sides of the concave plate 2, and the guide rods 21 pass through the guide sleeves 20. A pair of spring pins 35 are passed through the L-shaped seat 22, and a spring 36 is sleeved on the inner end of the spring pin 35. The spring 36 is located on the inner side of the L-shaped seat 22. A pull plate 37 is provided at the outer end of each pair of spring pins 35, and a connecting rod 38 is provided on the pull plate 37. A plug 39 is provided at the other end of the connecting rod 38. The axial direction of the plug 39 is perpendicular to the axial direction of the connecting rod 38. The plug 39 is provided with a limit plate 40, and the inner end of the plug 39 is a pointed cone structure.
