[0026] like Figures 1-10 As shown, this specific embodiment adopts the following technical solution: It includes a support frame 1, a rotating positioning rod 2, a concentric tightening wheel 3, a locking handle 4, a nut 5, a connecting frame 6, a washer 7, a push rod device 8, a cylindrical pin 9, a first fixing pin 10, a guide push plate 11, a locking block 12, and a second fixing pin 13. The support frame 1 is connected to the concentric tightening wheel 3 and the locking handle 4 in sequence through the rotating positioning rod 2, and is connected to the nut 5. The rotating positioning rod 2 can rotate within the circular hole of the support frame 1. The concentric tightening wheel 3 is installed in the connecting frame 6, and the connecting frame 6 is connected through... The screws are fixed on the support frame 1. Two arc-shaped guide grooves 301 are provided on the concentric tightening wheel 3. A gasket 7 is provided between the connecting frame 6 and the concentric tightening wheel 3. Push rod devices 8 are provided at both ends of the connecting frame 6. One end of the push rod device 8 passes through the connecting frame 6 and is set in the arc-shaped guide groove 301 of the concentric tightening wheel 3 by a cylindrical pin 9. The other end of the push rod device 8 is fixedly connected to the guide push plate 11 by a fixing pin 10. Locking blocks 12 are installed at both ends of the guide push plate 11 and are fixedly connected by several fixing pins 2 13.

[0027] The front end connector of the locking handle 4 is provided with a positioning hole 401. A spring 14 and a ball 15 are provided in the positioning hole 401. The spring 14 is fixed by a head screw 16. The connecting frame 6 is provided with a ball positioning hole 601. The ball 15 guides the front end connector of the locking handle 4 to move on the connecting frame 6. The front end connector of the locking handle 4 is connected to the concentric tightening wheel 3.

[0028] The push rod device 8 consists of push rod one 801, push rod two 802, and adjusting switch 803. Push rod one 801 and push rod two 802 are connected by adjusting switch 803. A spring two 804 is sleeved on push rod two 802. By rotating the adjusting switch 803, the adjusting switch 803 drives the screw at one end to move with the internal threads in push rod one 801 and push rod two 802, and pushes the guide push plate 11 to move outward or inward. Threaded rods are fixed at both ends of the adjusting switch 803. Push rod one 801 and push rod two 802 are provided with internal threads. The two internal threads are in opposite directions, adopting a one-forward-one-reverse design. By rotating the adjusting switch 803, rotating in the forward or reverse direction moves the threaded rods to rotate in the forward or reverse direction, thus pushing push rod one 801 and push rod two 802 to extend or retract. Extension pushes the locking block 12 forward to lock, and retraction pushes the locking block 12 backward to open.

[0029] A positioning support frame 101 is provided on the support frame 1. A positioning hole 1011 is provided in the middle of the positioning support frame 101. A push rod 802 on the push rod device 8 is inserted into the positioning hole 1011 for positioning.

[0030] The locking block 12 is provided with a locking groove 1201 that is adapted to the guide rod 17.

[0031] The support frame 1 has mounting holes 102 at both ends and is fixed to the machine body 18 by fixing pins. Guide rods 17 are provided in the guide holes on the left and right sides of the machine body 18. The upper end of the guide rods 17 is locked in the locking groove 1201 of the locking block 12. The locking device locks the machine body 18 while the guide rods 17 move up and down, and locks it by swaying left and right.

[0032] The guide push plate 11 is provided with an elongated hole 1101, and is vertically and vertically positioned and connected to the positioning hole above the machine body 18 through a screw. The elongated hole 1101 on the guide push plate 11 can move left and right along the screw, which is used to adjust the left and right movement of the locking block 12 fixed above the left and right guide push plates 11, thus completing the principle of locking and unlocking.

[0033] One end of the second spring 804 rests on the guide push plate 11, and the other end of the second spring 804 abuts against the positioning support frame 101. The locking and buffering function is completed through the cooperation of the elongated hole 1101 and the second spring 804. The small gap is automatically locked by the push of the second spring 804.

[0034] In this specific embodiment, by moving the locking handle 4, the concentric tightening wheel 3 is driven to rotate, and the cylindrical pin 9 at one end of the push rod 801 is pushed to rotate in the arc-shaped guide groove 301 of the concentric tightening wheel 3, which pushes the push rod 801 and the push rod 802 to move outward. At the same time, the locking groove 1201 of the locking block 12 at the upper end of the guide push plate 11 is fixed in the guide rod 17 and locked.

[0035] This specific embodiment has a reasonable structural design, is simple to install, and is easy to use. The locking handle drives the concentric tightening wheel to rotate, which in turn causes the pushing device to drive the guide push plate to move. The movement of the guide push plate causes the locking block to lock the guide rod, which plays a locking role on the woodworking planer. This effectively prevents the planing structure from moving under working vibration, ensures the accuracy of planing, and meets people's usage needs.
