According to the fishing device, the pull ring is pulled to drive the plug pin and the first limiting disc to compress the first spring, so that the effect of adjusting the depth of the fishing frame and the depth of the fishing net is achieved, the problem that fishing is inconvenient due to different water area depths and the distribution difference of floating objects is solved, and the adaptability of the fishing device to the complex water area environment is improved.

The utility model discloses a adjustable track saw relates to track saw field, including slide rail, the slide rail top is provided with cutting saw, cutting saw one side is provided with depth adjusting mechanism, and cutting saw other side is provided with angle adjusting mechanism. The utility model discloses the effect of depth adjusting mechanism, the depth of cutting saw cutting object is adjusted, and the first limiting axle is pushed manually to the inside of handle, and under the assistance of limiting boss, the first limiting axle drives the movement of limiting ring and two first bumps, makes the first bump from U -shaped piece arc groove remove, and cutting saw is turned over upwards around turnover base, after adjusting suitable angle, the push force that removes exerting on the first limiting axle, under the action of first spring, to limiting ring, exerts an outward push force to first bump, thereby the first bump is inserted into U -shaped piece arc groove, and U -shaped piece is opposite fixed with limiting rod, has the effect of adjusting cutting saw turning angle according to cutting depth demand, adapts to more cutting demand.

The utility model discloses a hanging basket type rape transplanter which comprises a frame body, a power input shaft is installed on one side of the bottom end of the frame body, wheels are installed at the two ends of the power input shaft, and an input chain wheel is installed at the position of the middle section of the power input shaft. Through the arrangement of the power input shaft, the middle transmission shaft, the planting device driving shaft, the seedling dropping driving shaft and the right-angle steering gear, conveying and transplanting of multiple rows of rape seedlings are achieved, the power input shaft receives external power and drives the chain assembly after driving, the power is transmitted to follow-up components, and then the rape seedlings are transplanted. The seedling dropping driving shaft can drive the four groups of right-angle steering gears, control the four groups of seedling dropping trays to rotate at a constant speed, drive four rape seedlings to enter the seedling dropping pipe at the same time and be input into the planting assembly, and multiple rape seedlings are transplanted at the same time, so that synchronization of seedling dropping and planting is realized, the transplanting efficiency is improved, and the device can better adapt to large-area transplanting.

The present application relates to the technical fields of micro-electro-mechanical system manufacturing, and specifically relates to a depth-adjustable mold for quartz glass hot forming and a method for adjusting the depth of the mold. The mold comprises: a ring-shaped mold cavity, the diameter of the ring-shaped mold cavity matches the diameter of a target resonant structure, and the original depth of the mold cavity is greater than the height of the target resonant structure; a concentric column, which is arranged at the center of the ring-shaped mold cavity and is concentric with the ring-shaped mold cavity, the height and diameter of the concentric column match the height and diameter of a support column of the target resonant structure; a sidewall air-extracting channel, the one-end outlet of the channel is arranged on the sidewall of the ring-shaped mold cavity, the one-end outlet of the channel is located at a preset height above the bottom of the ring-shaped mold cavity, and the channel is connected with an external vacuum pump; and a ring-shaped gasket, which is composed of one or more layers of gaskets and is arranged at the bottom of the ring-shaped mold cavity, and is used for adjusting the effective depth of the mold cavity. The present application solves the technical problems of the prior art, such as the unadjustable depth of the mold or the complex structure of the adjustable depth, and is suitable for the hot forming of micro-hemispherical resonant structures.
