[0023] To further understand the content, features and effects of the present invention, the following embodiments are cited and described in detail in conjunction with the accompanying drawings.

[0024] As Figures 1 to 4 shown, a manipulator with adjustable distance between the manipulator arms provided by an embodiment of the present invention includes: a mounting base 1, two groups of driving arms 2 are correspondingly arranged on the upper surface of the mounting base 1, a clamping arm 3 is rotatably installed at one end of the driving arm 2, and a rotating shaft 4 is arranged at the connection between the driving arm 2 and the clamping arm 3;

[0025] Specifically, as Figure 1 shown, during use, the driving arm 2 and the clamping arm 3 are integrally movably arranged. Therefore, when the driving arm 2 moves, the clamping arm 3 will move along the movement track of the driving arm 2, so as to achieve the effect of clamping an object; then the clamping arm 3 can be rotated at one end of the driving arm 2 through the rotating shaft 4, so as to adjust the distance between the clamping arm 3 and the driving arm 2, and increase the clamping space.

[0026] Furthermore, a driving assembly 5 is provided inside the mounting base 1, an adjusting assembly 6 is slidably installed on one side of the mounting base 1, one end of the adjusting assembly 6 is arranged on the driving assembly 5 for driving the adjusting assembly 6, and the other end of the adjusting assembly 6 is detachably connected to the clamping arm 3;

[0027] Specifically, as Figure 1 and Figure 3 shown, the design that the other end of the adjusting assembly 6 is detachably connected to the clamping arm 3. When in use, the driving assembly 5 is started to drive the adjusting assembly 6 to slide towards one end, so that one end of the clamping arm 3 expands along with the movement distance of the adjusting assembly 6, so as to adjust the distance between the clamping arm 3 and the driving arm 2, thus achieving the effect of automation and improving the convenience of use. At the same time, during the working process, the clamping range between the two clamping arms 3 at the upper end of the manipulator can be quickly adjusted, solving the problem of time waste caused by manual adjustment.

[0028] Furthermore, the driving component 5 includes a forward and reverse motor 501 and a lead screw 502. An installation groove 7 is formed inside the mounting base 1. The lead screw 502 is arranged in the installation groove 7, and the forward and reverse motor 501 is arranged on one side of the mounting base 1. One end of the output shaft of the forward and reverse motor 501 is fixedly connected to one end of the lead screw 502;

[0029] Specifically, as Figure 2 and Figure 3 shown, an installation groove 7 is formed in the mounting base 1, and the lead screw 502 is arranged in the installation groove 7. The mounting base 1 is used to protect the lead screw 502, so as to avoid dust falling on the outer surface of the lead screw 502, resulting in the situation that when the lead screw 502 is connected to other components, it is easy to have thread slipping and cannot drive other components.

[0030] Furthermore, connection sleeves 503 are slidably installed at both ends of the outer surface of the lead screw 502. One end of the connection sleeve 503 is provided with a connection block 504, and one end of the adjusting component 6 is arranged on the connection block 504;

[0031] Specifically, as Figure 2 and Figure 3 shown, when the forward and reverse motor 501 is started to drive the lead screw 502 to rotate counterclockwise, the connection sleeves 503 at both ends move away from each other. On the contrary, when the lead screw 502 is driven to rotate clockwise, the connection sleeves 503 at both ends move closer to each other, so as to drive the adjusting component 6 to slide horizontally, achieving the effect of convenient use.

[0032] Furthermore, a sliding groove 8 is formed on one side of the mounting base 1. The sliding groove 8 communicates with the installation groove 7, and the connection block 504 is slidably installed in the sliding groove 8;

[0033] Specifically, as Figure 2 and Figure 3 shown, through the design that the sliding groove 8 communicates with the installation groove 7, when the connection sleeve 503 slides, the connection block 504 can slide in the sliding groove 8 accordingly, thus avoiding the situation of jamming.

[0034] Furthermore, the adjusting component 6 includes a connecting rod 601. The connecting rod 601 is inclined. One end of the connecting rod 601 is fixedly installed on the connection block 504, and a fixing column 602 is fixedly installed on the upper surface of the other end of the connecting rod 601. The upper end of the fixing column 602 is detachably installed on the lower surface of one end of the clamping arm 3;

[0035] Specifically, as Figure 1 and Figure 3 shown, the connecting rod 601 is inclined, so that there is a certain distance between the connection block 504 and the starting position of the clamping arm 3. Thus, when the connection block 504 drives the connecting rod 601 to move, one end of the clamping arm 3 will expand outwards, so as to adjust the clamping arm 3.

[0036] Further, the connecting rod 601 includes a fixed rod 6011 and a movable rod 6012. One end of the fixed rod 6011 is provided with a movable groove 6015, and one end of the movable rod 6012 is provided with a movable block 6013. The movable block 6013 is slidably installed in the movable rod 6012. One end of the fixed rod 6011 is provided with an electric push rod 6014, and one end of the piston rod of the electric push rod 6014 is arranged on the movable rod 6012.

[0037] Specifically, as Figure 4 shown, the movement space of the mounting seat 1 is limited. Thus, when the connecting rod 601 moves to the limit, the electric push rod 6014 can be activated to push the movable rod 6012, so that the movable block 6013 slides outwards in the movable groove 6015 at one end of the fixed rod 6011, enabling the connecting rod 601 to be extended secondly and further expanding the clamping angle of the clamping arm 3.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
