[0024] In the embodiment, the left clamp body 11 and the right clamp body 12 are both straight plate-shaped, facilitating the installation of aluminum profiles with square or polygonal cross sections, and the left clamp body 11 and the right clamp body 12 are oppositely arranged to adapt to the outer shape of the aluminum profile.

[0025] The transmission assembly further comprises a transmission arm 22, which is driven by the drive source 3 and can drive the two groups of rotating arms 21 to rotate towards each other or away from each other to adjust the distance between the left clamp body 11 and the right clamp body 12; when rotating towards each other, the left clamp body 11 and the right clamp body 12 simultaneously exert force on the aluminum profile located between them to clamp and position the aluminum profile, so that the forces on both sides of the aluminum profile are balanced, avoiding the problem of unilateral deformation of the aluminum profile; when rotating away from each other, the left clamp body 11 and the right clamp body 12 simultaneously separate and lift the aluminum profile to facilitate the taking of the aluminum profile.

[0026] The opposite surfaces of the left clamp body 11 and the right clamp body 12 are detachably connected with rubber clamp pads 5, which can be adjusted in thickness according to different working conditions to adapt to the clamping of aluminum profiles of different sizes; in the embodiment, the bolt penetrates the left clamp body 11 or the right clamp body 12 and is threadedly connected with the rubber clamp pad 5, that is, after threadedly connecting, the head of the bolt is located outside the left clamp body 11 or the right clamp body 12, avoiding abutting against the aluminum profile.

[0027] The transmission arm 22 is rotatably connected with the support body 4 through a rotating shaft 9, and the transmission arm 22 is constructed as an isosceles bridge, both ends of the transmission arm 22 are provided with strip-shaped inclined grooves 23; the strip-shaped inclined grooves 23 extend along the middle part of the transmission arm 22, the rotating arm 21 is provided with notches 24 corresponding in thickness to the transmission arm 22, and the depth of the notches 24 is not less than the groove length of the strip-shaped inclined grooves 23; a pin shaft 6 penetrates the strip-shaped inclined grooves 23 and the notches 24, and both ends of the pin shaft 6 are fixedly connected with the rotating arm 21 at the side of the notches 24.

[0028] When the driving source 3 drives the transmission arm 22 to move upward, the interval between the left clamping body 11 and the right clamping body 12 is reduced by driving the two groups of rotating arms 21 to rotate towards each other by pushing the pin shaft 6 in the strip-shaped inclined groove 23 at both ends, and when the driving source 3 drives the transmission arm 22 to move downward, the interval between the left clamping body 11 and the right clamping body 12 is expanded by driving the two groups of rotating arms 21 to rotate away from each other by pulling the pin shaft 6 in the strip-shaped inclined groove 23 at both ends; that is, by using the principle of scissors, the output end of the driving source 3 realizes the adjustment of the larger interval between the left clamping body 11 and the right clamping body 12 under a relatively small stroke, thereby reducing the volume of the whole machine and reducing the space occupation.
