Preferably, described stopper slot is a rectangle, and the length of stopper slot is 100mm-200mm, and the width of stopper slot is less than the width of base.
The length of said through hole is less than the length of stopper slot, and width is 20mm-30mm.
The thickness of described fixed block and movable block is identical, and the thickness of fixed block, movable block is smaller or equal to the degree of depth of stopper slot, and preferred, the thickness of fixed block or movable block is 5mm-10mm.
Described fixed block is fixed in the stopper slot through fixed screw.
Described movable block is provided with the strip spacing hole, and spacing hole vertically is provided with, and is provided with limited screw in the spacing hole, and limited screw is fixed on movable block in the stopper slot.
The height of described support is greater than 80mm.The battery that the height of support can make things convenient for staff to take and fall from through hole greater than 80mm.
Described fixed block, movable block are the chamfering setting near a coboundary of through hole.Chamfering helps the placement of battery and the outward appearance of protection battery.
The beneficial effect of the utility model is:
The utility model can be adjusted movable block through regulating limited screw; Further the distance between adjustment movable block and the fixed block detects different specification of battery thickness to adapt to, and because the thickness of fixed block and movable block is thicker; It is less to wear and tear, and it is low to change frequency.The utility model highly versatile is applicable to the rectangular cell of different-thickness and width; Simple in structure, can reduce production costs; Detect accurately, can improve accuracy and efficient that cell thickness detects.
