The utility model discloses a cell culture bottle rack relates to cell culture device technical field. The cell culture bottle rack includes rack base, support platform, clamping unit, limit block, clamping block and locking unit, and support platform slidingly connects in the top of rack base. The cell culture bottle rack passes through the design of support platform, clamping unit and limit block, makes cell culture bottle convenient for clamping between two sets of limit blocks, keeps clamping stable, and cell culture effect is guaranteed, and simultaneously, through the design of limit block, clamping block and locking unit, makes limit block convenient for dismounting and replacement model, to adapt to multiple models cell culture bottle, ensures that the contact area between cell culture bottle and limit block is big during clamping process, and clamping effect is good, and safety is good, satisfies use demand.

The utility model provides a kind of engineering cost field surveying and mapping equipment, including latitude and longitude surveying and mapping instrument, latitude and longitude surveying and mapping instrument is fixedly installed on mounting plate, the bottom of mounting plate is hinged with several movable supports.The utility model has the beneficial effects as follows: when facing rugged use site, the length of adjustable supporting leg is extended from movable support, after length adjustment is completed, rotating knob is driven to rotate guide plate and rotating shaft, rotating shaft will drive rotating member to rotate, rotating member will push connecting rod to horizontal state, then connecting rod pushes clamping block to slide linearly in slide rail, the end of clamping block will be sequentially clamped in the clamping hole on supporting leg and the clamping groove on movable support, so as to lock fixing frame, movable support and supporting leg into one whole, then, push knob to slide on guide plate, so that knob is clamped into knob slot, realize the limit fixing of knob, achieve the purpose of locking mechanism limitation.
