[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0036] Please see Figures 1-5 An angle-adjustable L-shaped pin insert type fixing clamp includes a handheld angle adjustment mechanism 100 and a clamping assembly 200 for clamping L-shaped pins 300. The clamping assembly 200 is fixed inside the handheld angle adjustment mechanism 100, which is used to adjust the angle of the clamping assembly 200. The handheld angle adjustment mechanism 100 includes a ring seat 110 and a rotating seat 120 sleeved inside the ring seat 110 and capable of axial rotation. The axial rotational engagement between the ring seat 110 and the rotating seat 120 provides a rotational basis for subsequent adjustment of the angle of the clamping assembly 200. The clamping assembly 200 includes a fixed clamping piece 210 fixed in the rotating seat 120, a movable clamping piece 220 abutting against the rear end face of the fixed clamping piece 210, and a fixed seat 230 disposed on the rear side of the movable clamping piece 220 and fixedly connected to the rotating seat 120. The fixed clamping piece 210 and the movable clamping piece 220 cooperate to clamp the L-shaped needle 300, and the fixed seat 230 serves to fix the movable clamping piece 220.

[0037] like Figures 1-3 As shown, in this invention, a rotating cavity 111 is provided at the top edge of the inner ring of the ring seat 110. The rotating seat 120 has a hollow cylindrical structure and is fitted inside the rotating cavity 111. The rotating cavity 111 provides space for the rotation of the rotating seat 120, allowing the rotating seat 120 to rotate stably within the ring seat 110. A toothed ring 121 is provided at the bottom of the outer periphery of the rotating seat 120, and the toothed ring 121 overlaps the bottom of the rotating cavity 111.

[0038] like Figures 1-4As shown, specifically, the outer end of the ring seat 110 is provided with a handle 112, which provides a handhold for the operator to operate the fixture. An adjusting gear 130 is rotatably connected to the handle 112, and a gear ring 121 meshes with the adjusting gear 130. Through the meshing transmission between the adjusting gear 130 and the gear ring 121, the operator's operation of the adjusting gear 130 is converted into the rotation of the rotating seat 120. A rotating groove 112a is provided at the rear end of the top surface of the handle 112, which communicates with the rotating cavity 111. The adjusting gear 130 is disposed within the rotating groove 112a. The rotating groove 112a provides space for the installation and rotation of the adjusting gear 130 and ensures communication with the rotating cavity 111, guaranteeing normal meshing between the adjusting gear 130 and the gear ring 121. The adjusting gear 130 is coaxially connected to the rotating shaft 131. The rotating shaft 131 passes through the handle 112 and is coaxially fixedly connected to the rotating handle 132. The rotating handle 132 makes it easy for the operator to rotate the adjusting gear 130, so that the adjusting gear 130 is driven to rotate through the rotating shaft 131, making the operation more convenient.

[0039] like Figure 1 and Figure 2 As shown, further, an annular cover 113 is installed at the top of the ring seat 110. The annular cover 113 covers the toothed ring 121 and can protect the toothed ring 121, preventing dust, debris and other objects from entering and affecting the meshing transmission between the toothed ring 121 and the adjusting gear 130. At the same time, the annular cover 113 can prevent the rotating seat 120 from falling out of the ring seat 110.

[0040] like Figures 1-3 As shown, a first mounting groove 122 for mounting the fixing clip 210 is provided at the rear end of the rotating base 120. The first mounting groove 122 provides an accurate position for the mounting clip 210, ensuring the stable installation of the fixing clip 210 within the rotating base 120. A second mounting groove 123 for mounting the fixing base 230 is provided in the rotating base 120 on the front side of the first mounting groove 122. The second mounting groove 123 provides positioning for the installation of the fixing base 230, ensuring the correct connection between the fixing base 230 and the rotating base 120.

[0041] like Figure 1 and Figure 5As shown, it is worth noting that several guide posts 221 are fixed on the front end face of the movable clamp 220. The front end of the guide post 221 passes through the fixed seat 230 and is slidably connected to the fixed seat 230. The sliding cooperation between the guide post 221 and the fixed seat 230 provides guidance for the movement of the movable clamp 220, allowing the movable clamp 220 to move smoothly along the direction of the guide post 221. Several springs 222 are provided between the movable clamp 220 and the fixed seat 230. The springs 222 are sleeved on the outside of the guide post 221. The elasticity of the springs 222 allows the movable clamp 220 to remain in a state of abutment against the fixed clamp 210 when no external force is applied, thereby stably clamping the L-shaped needle 300. A dial ring 223 is fixed at the top edge of the front end face of the movable clamp 220. The dial ring 223 is used by the operator to move the movable clamp 220, allowing the operator to move the movable clamp 220 by turning the dial ring 223, making it convenient to release or clamp the L-shaped needle 300.

[0042] like Figure 5 As shown, it is worth noting that the bottom ends of both the fixed clamping piece 210 and the movable clamping piece 220 are bent, with the bending angle being the same as that of the L-shaped pin 300. This bending design allows for a better fit with the bent portion of the L-shaped pin 300, improving clamping stability. Several positioning grooves 240 are provided on the rear end face of the fixed clamping piece 210 and the front end face of the movable clamping piece 220. The L-shaped pin 300 is clamped in the positioning grooves 240, which position the L-shaped pin 300, ensuring accurate clamping and preventing displacement during clamping.

[0043] In this embodiment, the angle-adjustable L-pin insert type fixing clamp is used as follows: First, the operator holds the handle 112 and moves the movable clamp 220 backward along the guide post 221 by turning the dial ring 223. At this time, the movable clamp 220 compresses the spring 222, creating a gap between the movable clamp 220 and the fixed clamp 210. Then, the L-shaped pin 300 is placed into the positioning groove 240 and the dial ring 223 is released. Under the elastic action of the spring 222, the movable clamp 220 moves forward and engages with the fixed clamp 210. 0. Clamp the L-shaped needle 300; then, according to the machine installation position requirements, rotate the handle 132. The handle 132 drives the adjusting gear 130 to rotate through the rotating shaft 131. The adjusting gear 130 meshes with the gear ring 121, thereby driving the rotating seat 120 to rotate axially in the rotating cavity 111 of the ring seat 110, thereby adjusting the angle of the clamping assembly 200 so that the L-shaped needle 300 is adjusted to a suitable installation angle; finally, install the L-shaped needle 300 with the adjusted angle onto the machine to complete the installation operation.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
