Detailed Description
The present invention will be described in further detail with reference to the following specific examples, but the present invention is not limited to the following specific examples.
Examples
As shown in fig. 1-6, the present embodiment provides an egg picking tool for embryo laboratories, which includes a piston cylinder 1 and a piston 2 disposed in the piston cylinder 1; one end part of the piston cylinder 1 is provided with a sleeve hole 3 for sleeving a pasteur straw; a push button 4 capable of sliding along the axial direction of the piston cylinder 1 is arranged on the side wall of the piston cylinder; a piston rod 5 is arranged on the piston 2; the push button 4 is connected with the piston rod 5.
The push button 4 is connected with the end of the piston rod 5 through a slide sheet 6.
A strip-shaped hole 7 is formed in the side wall of the piston cylinder 1, and a sliding groove 8 is formed in the inner wall of the piston cylinder 1; one end of the sliding sheet 6 penetrates through the strip-shaped hole 7 to be connected with the push button 4, and the other end of the sliding sheet is in sliding fit with the sliding groove 8.
As shown in fig. 4, the end face of one end of the sliding piece 6, which is in sliding fit with the sliding groove 8, is an arc-shaped curved surface, so that the sliding resistance can be effectively reduced. The side wall of the slip sheet 6 is provided with a limiting block close to the strip-shaped hole 7, and the limiting block is used for limiting the radial movement of the slip sheet 6.
Scales are arranged on the side wall of the piston cylinder 1, and a pointer pointing to the scales is carved on the push button 4. Is used for accurately controlling the liquid suction quantity.
As shown in fig. 4, the upper end of the piston cylinder 1 has an end cap for limiting the maximum stroke of the push button 4. As an optimization, the end cover can be set as a screw cap, and further, the screw cap can be set as a screw cap with adjustable screw-in amount, so that the adjusting function of the maximum stroke is realized.
