The clamping platform is horizontally mounted on the upper end of the support rod, and a baffle is vertically mounted at the rear end of the clamping platform. The clamping column is slidably mounted on the clamping platform, with its rear end facing the baffle. Two arc-shaped cover plates are mounted opposite each other on the clamping platform to cover the clamping column. A fixing frame is mounted at the front end of the clamping platform, and a connecting frame is rotatably connected to the upper end of the fixing frame. A push-pull rod is mounted at the front end of the connecting frame, and the rear end of the connecting frame is rotatably connected to the front end of a connecting rod.

[0021] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0022] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0023] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0024] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0025] like Figure 1 As shown, this utility model embodiment provides a clamping device, which includes a base 2, a support rod, a clamping platform 14, and a clamping column. The support rod is vertically arranged on the top surface of the base 2, and a roller 3 and a locking mechanism 4 for locking the roller are arranged on the bottom surface of the base 2. The clamping platform 14 is horizontally arranged on the upper end of the support rod, and a baffle 12 is vertically arranged at the rear end of the clamping platform. The clamping column is slidably arranged on the clamping platform, and the rear end of the clamping column is opposite to the baffle 12. Two arc-shaped cover plates 6 are arranged opposite each other on the clamping platform to cover the clamping column. A fixing frame is arranged at the front end of the clamping platform 14, and a connecting frame 9 is rotatably connected to the upper end of the fixing frame. A push-pull rod 8 is arranged at the front end of the connecting frame 9, and the rear end of the connecting frame 9 is rotatably connected to the front end of the connecting rod 18. The rear end of the connecting rod is rotatably connected to the clamping column.

[0026] The clamping device provided in this embodiment of the invention utilizes rollers 3 for easy movement. Once the device is moved to the desired position, a locking mechanism locks the rollers, fixing the device in place and preventing further movement. In use, the workpiece is placed between the baffle and the rear end of the clamping column. Pushing or pulling the connecting frame down or up causes the clamping column to move back and forth on the clamping platform 14 via a connecting rod, thus clamping or releasing the workpiece. Therefore, this invention allows for convenient movement and effective workpiece clamping.

[0027] Furthermore, the clamping column includes a clamping cylinder 5 and a push rod, the push rod being threaded into the inner hole of the clamping cylinder. With this design, by rotating the push rod, the length of the threaded engagement between the push rod and the clamping cylinder 5 can be easily adjusted, thereby adjusting the length of the clamping column in the front-to-back direction, thus enabling the device to better clamp workpieces of different lengths or thicknesses.

[0028] Specifically, the push rod includes a round rod 13, a connecting rod 10, and a clamping block 11 opposite to the baffle. The round rod is threaded into the inner hole of the clamping cylinder. An elastic element is provided in the rear end of the round rod. The front end of the connecting rod 10 is connected to the elastic element, and the rear end of the connecting rod 10 is connected to the clamping block. With this design, the elastic element in the round rod provides good cushioning, preventing damage to the clamped workpiece. Preferably, the elastic element is a high-rigidity spring. It is understood that when the connecting frame is pushed backward by the push-pull rod, the connecting rod can drive the clamping cylinder and the push rod to move backward, causing the clamping block to gradually approach the baffle until the clamping block presses the workpiece firmly against the baffle. After maintenance, pulling the connecting frame forward uses the connecting rod to move the clamping cylinder and the push rod forward, causing the clamping block to move away from the workpiece, thus releasing the pressure on the workpiece.

[0029] Preferably, the locking mechanism is a brake pedal that can brake the roller, which is a commonly used component and will not be described in detail here; the base can be a rectangular structure.

[0030] Furthermore, the support rod is a height-adjustable support rod, which allows for convenient adjustment of the height of the clamping platform for ease of use.

[0031] Preferably, the support rod includes an upper rectangular rod 16 and a lower rectangular rod 1. The lower end of the upper rectangular rod 16 is slidably disposed within the lower rectangular rod 1. A threaded hole is provided on the side wall of the lower rectangular rod for engaging with the threaded section of a locking screw. Using this design, the lower end of the upper rectangular rod slides up and down within the lower rectangular rod, allowing adjustment of the support rod's height. The height of the clamping platform is thus adjusted accordingly. After reaching the desired height, the locking screw is used to press the lower end of the upper rectangular rod firmly into the lower rectangular rod, locking the upper rectangular rod and preventing further change in the support rod's height, thus preventing further downward movement of the upper rectangular rod. Specifically, the threaded hole can be located on the upper part of the right side wall of the lower rectangular rod.

[0032] In one specific embodiment, the fixing frame includes two vertical plates 19 arranged relatively vertically on the left and right sides of the clamping platform; there are two connecting rods 18, located on the left and right sides of the clamping column respectively; the connecting frame 9 is an inverted U-shaped frame, with the lower ends of the two side plates of the connecting frame rotatably connected to the two vertical plates respectively, and the upper ends of the two side plates of the connecting frame rotatably connected to the front ends of the two connecting rods respectively via connecting pins 15. It is understood that the rear ends of the two connecting rods are rotatably connected to the left and right sides of the clamping cylinder respectively; the arc-shaped cover plate located at the rear will not interfere with the movement of the connecting rods.

[0033] Preferably, the top surface of the clamping platform is provided with an arc-shaped groove for fitting and sliding with the clamping cylinder, so that the arc-shaped groove and the arc-shaped cover plate can better limit and guide the forward and backward sliding of the clamping cylinder.

[0034] Specifically, a rubber anti-slip handle 7 is provided at the end of the push-pull rod 8 away from the connecting frame, so that the connecting frame can be pushed and pulled more conveniently, and the push-pull rod can be prevented from slipping out of the hand.

[0035] This utility model is easy to move and the height of the clamping platform can be adjusted according to the user's needs. It can clamp workpieces of different lengths or thicknesses and has the functions of a bench vise and a handheld gripper, which can improve maintenance efficiency.

[0036] Although specific embodiments of the present invention have been described in detail by way of examples, those skilled in the art should understand that the above examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention. The scope of the present invention is defined by the appended claims.
