The utility model relates to the technical field of spraying, and discloses a mold which is suitable for assisting in spraying paint on corners of a structural body, each corner is formed by connecting a plurality of structural surfaces arranged at an angle, the mold comprises a plurality of plates which are arranged at an angle and fixedly connected, the plates are suitable for being arranged on the structural surfaces of the corners respectively, and the plates are arranged on the structural surfaces. Notches are formed in the to-be-sprayed areas, corresponding to the corners, of the edges of the plates, the notches of the multiple plates are suitable for being defined to form openings corresponding to the to-be-sprayed areas, and constructors are suitable for spraying paint to the to-be-sprayed areas through the openings. According to the mold provided by the utility model, the plurality of plates are arranged at the corners, and the openings corresponding to the to-be-sprayed areas are defined by the plurality of notches, so that other areas, except the notches, of the plates can shield non-sprayed areas near the to-be-sprayed areas, and therefore, measurement and positioning and pasting of masking paper at each corner are avoided; and the masking paper can be prevented from being removed after spraying is completed, and the working efficiency can be improved.

The utility model discloses a film storage device which comprises a box body, a second fixing frame is fixedly connected to the interior of the box body, a placing frame is slidably connected to the interior of the second fixing frame, fixing frames are fixedly connected to the interior of the box body and located above the second fixing frame at equal intervals, and partition plates are slidably connected to the interiors of the fixing frames at equal intervals. The film fixing device has the advantages that the partition plates can slide to drive the second limiting blocks to move, and the distance between every two adjacent partition plates can be adjusted according to the size of a film of a patient; and a second limiting plate pushes a second limiting block to enter a limiting groove under the elastic action of a third spring to limit a partition plate, so that the films are prevented from moving at will, the requirement of doctors for placing the films is met, and the practicability of the device is improved.

The utility model discloses a camber beam motorcycle starting lever which comprises a foot rest lever, the inner wall of the foot rest lever is fixedly connected with two first springs, the upper ends of the two first springs are both fixedly connected with first clamping blocks, the upper surfaces of the two first clamping blocks are both movably connected with pressing blocks, one ends of the two pressing blocks extend to the outer portion of an adapter block, and the other ends of the two pressing blocks extend to the outer portion of the adapter block. The inner wall of the foot rest lever is slidably connected with a clamping column, the inner wall of the clamping column is fixedly connected with a second spring, the upper end of the second spring is fixedly connected with a second clamping block, the side face of the clamping column is in threaded connection with a nut, the foot rest lever is sleeved with an anti-skid sleeve, and one end of the second clamping block extends out of the anti-skid sleeve. A first spring, a first clamping block, a pressing block and a limiting rod are matched with one another, replacement can be conveniently carried out when the pedal rod is damaged, time can be effectively saved, a clamping column, a second spring, a second clamping block and a nut are matched with one another, a new anti-skid sleeve can be conveniently replaced when the anti-skid sleeve is seriously abraded and loses the anti-skid function, and the anti-skid sleeve is fixed more firmly.
